Monitors the order and asymmetry of
phases and the presence of voltage on
the 3 phases of a three-phase circuit
(power supply of a motor, etc.)
iRCI
Current control
b
b
Monitors the current flowing in a
circuit and indicates any crossing
of the set threshold
Time delay relays are used in service sector
and industrial buildings for small automatic
control systems: ventilation, heating,
animation, roller blind servo controls,
escalators, pumps, lighting, signalling,
monitoring, etc.
iRBN and iRTBT relays can interface
automatic control system inputs/outputs
with low-voltage devices.
Control relays monitor electrical
parameters and indicate when they are
exceeded
